120 INSECUTOR INSClTLt MENSTRUUS 



The lack of cell M\ is not a generic character since it occurs in various 

 species in genera of many tribes (Limnophila, Polymera, Eriocera, etc.). 



G. nigra Brun. (p. 494) stated in a long text discussion to lack the 

 radial crossvein, but this is very clearly shown in the figure (pi. 1 0, fig. 3). 



Cladura flavescens Brun. (p. 501) is very probably a Limnopbiline, 

 strongly suggesting Adelphomyia Bergroth. 



Claduroides fascipennis Brun. (p. 305), Rhaphidolabis fascipennis 

 Brun. (p. 5 1 9), and Gnophomyia longipennis Brun. (p. 489) are almost 

 certainly one and the same species.
